135-5(x+4)=35
5(x+4)=1355-35=100
x+4=100:5=20
x =20-4=16
ai k mình mình k lại
Ta có: 135 - 5(x + 4) = 35
\(\Rightarrow\) 5(x + 4) = 135 - 35
\(\Rightarrow\) 5(x + 4) = 100
\(\Rightarrow\) x + 4 = 100 : 5
\(\Rightarrow\) x + 4 = 20
\(\Rightarrow\) x = 20 - 4
\(\Rightarrow\) x = 16
Vậy: x = 16
135 - 5( x + 4 ) = 35
5( x + 4 ) = 135 - 35
5( x + 4 ) = 100
( x + 4 ) = 100 : 5
x + 4 = 20
x = 20 - 4
x = 16
KL : x = 16
135 - 5 ( x + 4 ) = 35
5 ( x + 4 ) = 135 - 35
5 ( x + 4 ) = 100
x + 4 = 100 : 5
x + 4 = 20
x = 20 - 4
x = 16
135-5(x+4)=35
135-5x-20=35
-5x=35+20-135
-5x=-80
x=16
135 - 5( x + 4)=35
5 ( x+ 4 ) = 135 - 35
5 ( x + 4 ) = 100
x+ 4 = 100 :5
x+ 4= 20
x = 20 - 4
x = 16
Ủng hộ tui nha .b! ^.^
tk mk nha
135 - 5(x + 4) = 35
5(x + 4) = 135 - 35
5(x + 4) = 100
x + 4 = 100 : 5
x + 4 = 20
x = 20 - 14
x = 16
\(135-5\left(x+4\right)=35\)
\(5\left(x+4\right)=135-35=100\)
\(x+4=20\)
\(x=16\)
